Application Decemberj, 1941, Serial No. 422,144 9 Claims. (Cl. 100e-25) This invention relates to baiing presses and more especially to the-means employed for plac-` ing under compression'the material to be hailed):

An object of the invention is to provide a coin-V pressing head mounted in a new and novel mani ner whereby the continuous rotation of a driv shaft will produce a combined oscillating and sliding motion oi the head with the result that material supplied to the press will be directed into and compressed within the baling chamber:

A `further object is to provide mechanism of this character which operates to speed up the baling operation and materially reduces the power required to form a bale.

Another object is to provide baling mechanism which is durable and compact in consti-cction and formed of few parts.

With the foregoing and other objects in View which will appear as the description proceeds;- the invention consistsl of certain `novel details o f construction and combinations of parts herein-` after more fully described and pointed out in the claims, it being understood that changes' `may be made in the construction and arrangement of parts without departing from the spiritof the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure' l is a central, vertical, longitudinal section through that portion of a baling press constituting the present invention.

Figure 2 is a top plan View thereof.

Figure 3 is a section on line 3-3, Figure l. l

Figure 4 is a section on line 4 4, Figure 1, but showing the compressing head in the dotted line position villustrated in Figure 1.

Referring to the :figures by characters of reference, l designates the baling chamber of the press` the same being .extended from but opening into a substantially cylindrical intermediate chamber 2 into which opens a eed chamber 3f, the latter chamber and the 'paling chamber rI being preferably coaxial as shown particularly in Figure 1.

Oppositely extending alined bearing studs 4 are `carried by the side walls of the intermediate chamber 2 at the centers thereof and mounted for rotation on these studs are Wheels -5 connected by a cross-rod 6. In order that the movement -of this rod during back and forth rotation of the wheels 5 may not be interfered with, an arcuate slot 'l is formed in each side wall -of the intermediate chamberv 2. The length of each slot is equal to the length of the path oi movement of the rod i5.

Each of the wheels 5 carries an arcuate series of teeth 8 in the form of regularly spaced pins and meshing withthe pins of the respective series are gears 9 rotatable with a transverse shaft I0. This shaft is journaled in slides II mounted for up and down movement within guides I 2 `mounted upon the top of chamber 2. A pulley I3 can be secured to shaft Ii) so as to receive motion from any suitable source through a belt I4. The guides I2 and the slides Ii are so proportioned that when the slides are in their lowermost positions, the'gears 'S will be positioned where they can rotate'beneath the engaged' pins 8 whereas, when the slides are raised, the gears 9 will be supported on the pins 8 while meshing therewith. Thus when the ygears 9 are rotated continuously in one direction as indicated, for example, by the arrow in Figure 1, they will drive the wheels 5 in a counter-clockwise direction until the pin-s at one end of the series reach positions beneath the shaft lil. Thereafter the shaft and the gears 9 will drop to their lower positions and the continued rotation of the gears will result in said gears driving the teeth in a clockwise direction until the teeth at the other ends of the two series are reached whereupon gears '9`will move upwardly around said end teeth and reassume raised positions. This, obviously, will result again in driving the wheels in a counter-clockwise direction. Thus as the gears 9 continuously rotate in one direction, the wheels 5 Will be rotated back and forth, the distance of movement 'being such as to cause rod t to move Within the .slots l. from one end to the other of the slots.

Located at the sides of the intermediate chainber 2 adjacent to the inlet end I 4 of the baling chamber l are forked 'guides in the form of arcuate channels IS or the like which diverge upwardly and downwardly toward the top and bottom of the inlet I4 from intermediate pockets I6 which are positioned `in the same 'horizontal plane with the axis of rotation of wheels v5 and with the longitudinal centers of the chambers i and 3. Mounted in these guides are anti-friction rollers I'I carried by the sides of the compressing head I8 adjacent to one end thereof, the .opposite end portion oi' this head being connected to and movable with the rodr As shown naiticularly in the drawings the compressing head I8 has its opposite faces flat, Aone being a duplicate of the other and the head 'is so proportioned that when the 'antifriction `rollers il are located in one end of the guide I5, the rod 6 carrying the other end of the head will be so positioned that the head will bridge and be supported close to the inlet end I4 of the baling chamber I.

That end of the head I8 connected to the rod 6 has a shearing blade I9 connected thereto, said blade being provided with oppositely disposed cutting edges 2U. These edges are adapted to cooperate with cutting edges 2| of blades 22 which are secured to opposed walls of the feed chamber 3 and can be adjustably mounted if s'o desired.

Assuming that the shaft I is rotating continuously in the direction of the arrow shown in Figure 1 and the parts are positioned as shown by full lines in said figure, it will be apf- 'f Y parent that further rotation of said shaft will result in the gears 9 moving past the engaged vpins 8 so that the gears thus will drop to their lower positions while remaining in mesh with the adjacent pins. Further rotation ofthe shaft and gears will result in rotation of the wheels 5 in a clockwise direction. If material to be baled has been supplied to the intermediate chamber from the feed chamber 3, the rotation of the wheels 5 in a clockwise direction will result in rod 6 moving away from the position shown by full lines in Fig. l and along the slots 1, dragging with it the compressing headIB. This will result in the head sweeping up all of the materia1 in the path thereof and at the same time pulling the antifriction rollers I1 along the upper portions of the guides I5 into the pockets I6. The advancing cutting edge of the bladeIS will cooperate with the cutting edge 2I at the top of the chamber 3 to shear off any material which may be extended Y outwardly past the blade I9. When rod 6 reaches the horizontal plane occupied by the axis of rotation of wheelsl 5 and begins to move upwardly from said plane, rod 16, as it moves toward the upper endl of the slot 1, will thrust the head I8 so that the anti# friction rollers I1 will move downwardly toward the lower` ends of the guides I5 until rod i6 reaches the upper end of slots 1 whereupon the head I8 will have been brought into position across the inlet I4 of chamber I with rod 6 uppermost and rollers I1 lowermost. While mov- I all of the material in the path thereof and during such movement additional material ,to be baled can be fed into chamber 2 from the feed chamber 3 where it will occupy the space back of head I8. As soon as the rod 6 reaches the upper ends of slots 1, gears 9 reach one end of the series of pin-teeth 8 and ride aroundn'the same to assume a position above the path of movement of the pin-teeth. Thus continued rotation `of shaft I0 will result in moving the wheels 5 in a counter-clockwise direction and, as a result, the rod 6 will move away from the upper ends of slots 1, pulling the head I8 therewith until the antifriction rollers are raised into the pockets I6. As rod 5 moves downwardly past the longitudinal center of the press it will exert an upward thrust against head I8, causing the rollers I1 to move upwardly within the guides until the head is returned to the position shown by full lines in Figure 1; C'onsce'ojuentlyl the material previously deposited back of the head will be forcibly expelled through inlet I4 into the baling chamber I. Thereafter 4the operation already described will be repeated, the wheels 5 rotating back and forth and causing the head I8 to swing and slide to the two positions described so as to convex walls of the upper portions of the guides.

Obviously every time the head is moved in a direction to force material in the path thereof, one of the cutting edges 20 will engage one of the cuttingredges 2I to shear off the material in the path thereof.

It is to be understood of course that the constructionv of the baling press can be modified as desired without departing from the spirit of the invention as claimed and while slots 1 have been shown to permit movement of the rod 6, it will be understood of course that any clearance perf mitting such movement may be employed.

Importance is attached to the fact thatthe head I8 constitutes both a sweep and a compressor, each operation of the head serving to sweep material from the chamber 2 into the inlet I4 and the two faces of the head being brought s`uccessively into compressing position.
